  • Application of DC Resistance Tester in practical operation

    ​DC resistance test is an indispensable test item after the transformer is handed over, overhauled and the tap changer is changed. Therefore, it is very important to use a DC resistance tester to test the DC resistance of the transformer. Routine maintenance and good use of the DC resistance tester. The operation is very important for the normal operation of the DC resistance test. Therefore, it is necessary to solve the problems existing in the practical application and management of the DC resistance tester in a timely manner.

  • How to ensure the transportation of DC resistance testers?

    The transformer DC resistance tester is commonly used to measure the DC resistance of large capacity transformers. It is a high-precision stable current power supply and testing part designed as a whole. The testing process is controlled by a microcomputer and automatically completes stable current judgment, data acquisition, data processing, resistance value display and printing. This instrument can complete the longitudinal test of the on load voltage regulator with one power supply, fully saving test time.

  • What are the precautions for using a zinc oxide lightning arrester tester?

    ​1. Do not plug or unplug the measuring wire when inputting current and voltage to avoid damaging the zinc oxide lightning arrester tester.

  • The principle and significance of testing methods for grounding resistance in substations

    ​In recent years, many substations in China have experienced expanded accidents due to lightning strikes. Most of the grounding resistance related to the grounding grid is unqualified, which plays a role in working grounding and protective grounding. When the grounding resistance is too high, a grounding fault occurs, and the neutral point voltage offset increases, which may cause the sound phase and neutral point voltage to be too high, leading to equipment damage and exceeding the required insulation level.

  • How much do you know about insulation resistance testers?

    ​The Insulation Resistance Tester is a universal high-voltage measuring instrument that can be used for measuring AC high voltage and DC high voltage in power systems, electrical appliances, and electronic equipment manufacturing departments. The insulation withstand voltage tester is composed of a high-voltage measurement section and a low-voltage display instrument. During work, the high-voltage section and low-voltage instruments are separated, ensuring reliable operation. It has a portable structure, and the entire machine uses an aluminum alloy packaging box as the casing, which is very convenient to use and carry.

  • Measurement Methods Of High Voltage Generator

    We lay out practical DC high‑voltage generator measurement methods for power‑equipment insulation tests. We address shielded microammeter use, zinc‑oxide arrester leakage‑current testing, surface‑leakage control and safe discharge steps for different‑capacitance equipment. Citing IEC and OSHA standards, Weshine Electric provides this guidance as a technical reference for qualified power‑testing professionals.
